- See also: Seventy-nine sentinels
The sentinel is a tall coniferous evergreen tree. It has grey-green needles, and produces a sweet, sticky sap from its trunk. Sentinels are found throughout much of Westeros: including the North, beyond the Wall, the Vale, the Riverlands, the Crownlands, and the Stormlands.
Three green sentinel trees are used on the coat-of-arms of House Tallhart.
